Abstract

An infusion set for subcutaneous delivery of an infusant. The infusion set may include a base removably attachable to an infusion site and a connector temporarily lockable to the base. The connector can engage the base in a plurality of orientations. The connector locks into the base after at least partial rotation of the connector about the base. The connector may include flexible arms which unlock the connector from the base. The base includes a cannula for insertion through the infusion site. The connector includes a tubing for passing the infusant. The infusant is subcutaneously passable from the tubing through the cannula when the connector is attached to the base. The infusion set may also include a hub removably attachable to the base that includes a needle that extends through the base and the cannula and a guard removably attachable to the base opposite the hub for surrounding the needle.
